Application filed August 31, 1921. Serial No. 497,285.

To all whom t may concern:

Be it known that I, ALBERT T. POTTER, a citizen of the United States ofAmerica,re siding at Detroit, in the county of Wayne and State ofMichigan, who Ahave invented certain new and useful Improvements inl/Vindshield Construction, of which the following is a specification,reference being had therein to the accompanying drawings.

In the `construction of wind-shields for motor vehicles and particularlythose where the upper and lower sashes or panels are hinged and overlapat their adjacent edges, it is common to place a rubber weather stripover the upper edge of a glass panel to abut the glassof the upper paneland make a tight joint so that the rain can not beat through the crack.The glass panel of the lower or .inner sash to which the Weather stripis applied, is held at the upper corners of the panelby suitablecastings and these castings abutting the castings on the upper sash holdthe sashes apart and itis necessary to stop the weather strip adjacentthese castings thus leaving a crack at eachcorner` of the frames throughwhich the rainwill work its way and get into thecar.

The object of this invention is to provid a simple construction whichmay be employed in connection with windshields as commonly constructedand wherein provision is made for extending the weatherstrip past thecorner irons and thus sealing the joint at the corners of the frames aswell as throughout the length of ythe glass panels. f

A further object of the invention is-to so construct these corner ironsvas tojffacilitate the application of the glass panelto the frame,preventing breakage of the ,panel Where it is necessary to notch thecorners thereof to receive the corner irons.

A further object is to provide 4certain other new and useful featuresinthe construction :and arrangement ofI parts, all as hereinafter morefully described.

With the above and other ends in view, the invention consists inthematters hereinafter set forth and more particularly pointed out inthe appended claims, reference being had to the accompanying drawing inwhich t Figure l is an elevation of the portions of a windshield and itssupport illustrating the application of the invention theretor andshowing parts broken away and in section to moreclearly disclose ktheconstruction;

A, Fig. 2 is' a sectional,.detaily substantially j upon the line 2 2y of F ig. l; I f Fig. 3 is a `sectional detail showing the wind-shieldframes in `end'elevation with the corneriron of the lower frame invertical section; andl v Fig. t is a perspective view of a corner iron.i

In, theconstruction shown in 'the accom-4 kpanying drawing l indicatessuitable side' supporting members for,y ythe ywind-shield which arecarried by the body of the car and form rigid supports for thewindshield to which the, windshield frame is pivotally attached, thelowery framekm'embers 2 forming the ends of the frame being pivotallyattached, as atB, tothe supports l. The end members 4 of the upperframe-or sash are pivotallyy supported in any suitable manner (notshown)l by the ,supportsl andare in the vertical fore-and-aft planes ofthe ment bers 2 ofthe `lower frame. v 5 indicates the glass panel oflthe lower sash or frame and '6 the glass panel of the upper sash andthe` posejupon the upperv ends of the tubular framey members 2gof the`lower sash,these corner members 8 beingl specially constructed andembodying the invention.

k'Each ofthese corner members 8 comprises a socket` portion 9 to receivethe upper end ofthetubularfframe member 2, forming a cap for closing theend of the tubular member and being also provided-'7.- withv laterallyextending yparallel ears 10 adapted to embrace the glass panel 5`adjacent each corner thereof toA hold the glass in place. A glassreceiving channel 11 is thus formed between the ears 10 and the cornermember isy pro,- vided with yan upstanding rib l12 with its inner end inalignment with the channel l1, said lrib being curved laterally toconform somewhat to thecurved rear side wall of the closed bya rubber-Weather strip 13 of channelforin, the-channel ofthe weather stripbeing-of a' width to litcloselyover the upper edge of the glass 5. lTheside of the weather strip toward the panel` 6 is formed with asupplemental lip or tongue 11 which is yfree along'its lower edge andtends to springout-y wardly away from the body of the strip into firmcontact with the glass panel 6 and ythus close the space between theadjacent edgeportions of the two-panels, the tongue 11 forming a-yieldable vportionofthe strip so thatethe panels may-be swung towardeach other and compress this side of the weather strip slightly rtoinsure'a tight joint.

The weather: strip is extendedy atrv its ends beyond the upper edge ofthe panel 5 and engaged 4over the-ribs112provided upon the twocornerirons 81of the lower sash.- The end portions vof the weatherstrip' are therefore continued tothe full widthof the lower sash, vbeingheld -in f place upon vthe corner ir-onsby engaging the upstandingflanges 12. As these fina-ges are-curved flaterallyfaway from fvtheupper sash, the weather strip' makes a tightjoint between the cornerirons Sonthelower sash and the'cornerA irons 7 on the Iuppersash-without holding the sashes spacedso far apart that the weatherstrip will Inot engage'theglass panel 6'of the upper sash and' fill thespace` between the panels. Aftight jointisA therefore formed by theweather; lstrip between vthe sashes lthroughout their entire length. I f

- In orderfthatthe upper edge ofthe panel 5 maybe flush with the upperedge of the rib 12 so `that said edge and rib will" form a continuoussupport for they channeled weather'rstrip,` saidpaneliscut alway ornotched, as at 15, at each of its upper cor j ners, and thefcaistin'gforming each corner iron .8 is cut away, as at 16,-"between- `itsflanges 110= to Aobviate the necessity for formin'gI a square' corner'notch in the glass but this' notchfm'ay be formed, as shown, with arounded corner! which ismuch veasier to eut thana; square corner andalso adds strength to 'thevglass so that the panel is not nearly asliable to crack inwardly'from this rounded cornery as `itrvwould be ifVthe-corner `were formed by edges meeting at an angle. `Further,fa-roundvcorner may be ground in the manufacture lof the panel-withoutdanger of cracking theglassg w1`1i1e a square corner is difficult-ttocut' without crackingI the panel.

.out their entire length.

The glass panels of wind-shields of this type as :commonlyconstiaicted,are` notched at the corners to permit the upper edge of thepanel to extend upwardly to the plane of the top of the corner -ironsand topermit the side edge of the panel to engage the channel 17 of thetubular frame members 2 and 4.

with sharp inner angles, -due to the construction' of the cornerIirons', but maybe formed with rounded hinner angles, thusfacilitatingmanufacture and greatly reducing thefiliability of breakage. f U rlheribs 1 2 on the corner irons 8 form continuations ofthe upper edge ofthe glass panel 5 and-thus a firm and vrigid-'support for the endportions of yth'e 'channeled weatherA strip -are providedand atight-joint is secured bet-ween the two sashes through* Obviously,changesmay bemade in the form andf'construction of the `devicewithih thescope of the appended claims without des parting lfrom the spirit of theinvention, and do notthereforel-imit myself tothe particular form orarrangementshown.` Having thus fully described' my invention, what I'claimI is Y l l `1 .'-A corner member for windshield sashes wherein saidsashe'scomprise end iframe members and glass panels held by said framemembers with vfree edges of the panels in overlapping relation;y saidcorner members comprisingy -a socket l"portion yto freceive the end ofan end frame member,-an.d anup standing 'portion forming a=continuatio`n of the free edge ofthe'glasspanel and-fo-H'set laterallyto overlap -la f socket portion of1 a corner member on an overlappingsash, said upstanding portion being "adapted tof engage anend'` portion:olf-fa channelof 'a weatherstrip on said free edge of said glasspar-ie'lf 42.
